  4. Controlling extra injector with thunder ecu

    Where are you logging intake temps ? 

    Similar setup but with 4 cyl 

    I have a single channel egt as low as i can get in the port floor of my now non intercooled methanol bike and with temps like 17c at 25psi i dont see the need to have more than a slightly rich mixture to control intake temp

    Thanks Adam
    The Toyota coils look good for clearance in the 1UZ version  and may have to look at aftermarket versions for the power needs 
    R35 GTR  read well in doing a bit of a search 
    i think the 051 connector position would be a problem 
    Audi coils any good ? again the size may beat me 

     

    Think i will trawl the wreckers for samples and see what is best fit 

    Also some good reading  from platinum racing comparing the R35 and 1UZ coils and SQ engineering on the  various toyota versions 
    R35 look to have big dwell time anywhere you see them listed or discussed

    Hey all,
    figured there is a wide range of experiance on this forum 

    Looking for smart pencil coils that are compact and powerful
    this is for motorcycle application , so space is limited on the top section
    and running E85 at 3 bar or higher and potential at Methanol 

     

    I have LS2 truck coils on a couple of my LSR bikes and they work great on all fuels i have used   or but there just too bulky  for some of the bikes  
    thanks in advance

    Oh had the old melting coils  with power on motor not running  the other day , trying  a Haltech ignitor something i dont usually run but seemed simple setup at the time  to get a new setup timed  (the CDI i would have run was not triggering the timing light at cranking )

    I am set to falling edge trigger , could the haltech be rising edge ?

    Not too different to mine , 31 deg at 14 psi and down to 26 by 28 psi, i think there is a lot more in it but as the bike is only landspeed racing on salt  and i am more traction limited than hp,  reliability for WOT for a 90-120 seconds is more important than peak power  , and i know what you mean by time  to check, i do want to spend a lot more time esp as e85 and flex fuel look to be my next step

    Hi Andrey

    We also haver used a link G4 extreme  on a GSXR 750  now a Vipec v44

    set to BAP/MAP/X over , as we see a lot of altitude change between venues and wanted better barometric correction 

    main tables are rpm/tps , with a 4d  removing fuel MAP based when the turbo system begins to loose effiancy above 24 psi 

    ign is  RPM/MGP , currently fairly conservative , but intending to do more work on it

    Thanks Dave 

    Suppose my personal conversion to Vipec will be complete when i start using your forum ;)    time to create an account 

    If i have an issues i will keep this thread running as its relevant to the Storm  and staged injection anyway

    Hi 

    I have been running sequential staged on a 750cc turbo motorcycle with a g4 extreme 

    that ecu is now gone but still have the PCL and about to be replaced by a v44 , besides the wiring changes needed  , and the software conversion 

    is there anything with the change from seq to grp staged that will effect the tuneup enough i cant sort with logging 

     

    Thanks
